| 0:00.0 | This is CBSI in the world with David Livingston Hotel Mars episode N. We're speaking with the |
| 0:10.2 | astronomer Patrick Sophia LaCoffke. Patrick's just explained to us the different |
| 0:16.0 | kinds of Nepp transneptunian objects that need to be explained in some fashion. Some are |
| 0:21.4 | a severe inclination to the solar plane. Some are independent of Neptune. Some are |
| 0:27.4 | in resonance with the four large planet Saturn Jupiter Uranus and Neptune. And some are independent, |
| 0:36.3 | independent in a fashion that is odd. What are they resonating with? David, you have a question. |
| 0:43.1 | Since these are objects, is it possible that the James Webb or Hubble can spot them if you know |
| 0:50.0 | where to look? That's a good question. This question is related to what should they do in order to |
| 0:58.4 | validate these hypotheses? So there are two ways. One is of course to observe directly |
| 1:06.6 | find this hypothetical or mass planet. You think one planet or two, I'm sorry I'm confused. |
| 1:14.4 | You're looking for one planet? One, one. We just consider one hypothetical planet. Please continue. |
| 1:21.1 | Yes. And the second approach is to try to find new, new transneptunian objects with |
| 1:29.2 | extremely peculiar orbits that we predict to exist because of the perturbations of this |
| 1:34.0 | hypothetical planet. So in that case, honestly I'm not an observer so I'm not sure how James Webb |
| 1:43.5 | could help, but I can say that in order to find this new transneptunian objects, which would |
| 1:53.2 | lead to an indirect confirmation of the presence of this planet, we should observe |
| 2:00.7 | very slow-moving objects. In other words, very distant from an action perspective, |
| 2:06.5 | and also highly incline objects. So we should look at this trying to find more of these populations |
| 2:13.6 | in order to first have indirect evidence of this planet. So basically large-scale surveys would |
| 2:22.7 | be needed. So I'm not sure if James Webb test would be able to do that. I guess I presume that |
| 2:29.1 | the field of view is not so large to perform such a large scale survey, but that's what I can |
| 2:36.4 | say at the moment. And do you give this hypothetical planet a name? Is it a planet nine had a name? |
